Why buy from us?

Onkyo A-9070 and KEF Q950 Stereo Hi-Fi System delivers room-filling sound with clarity and power, it features high-end technologies like Uni-Q driver array, damped tweeter loading tube speakers. On top of high-end speakers, Onkyo A-9070 is a serious sound amplifier that dampens frequency distortion and vibration, closed-circuit design and highest build quality, that not only focus on powerful sound but eliminates noise to let you enjoy pure music.

Onkyo A-9070 4 Channel Stereo Integrated Amplifier

Onkyo A-9070 Audiophile Integrated Amplifier, New DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) dampens super high frequency distortion. Closed ground-loop circuits, HICC (High Instantaneous-Current Capability), and vibration-damping construction combine to produce a startlingly pure sound across a wide dynamic range. The unit's four 15,000 µF capacitors keep plenty of power at the ready. Efficient parallel push-pull amplification paired with three-stage inverted Darlington circuitry works at reducing distortion to almost nil. Separate Wolfson® 192 kHz/24-bit DACs for both left and right channels improve performance. The unit is also equipped with 192 kHz/24-bit HD audio playback to handle modern formats. Four discrete amplifier modes integrated amp, power amp, pre-amp, and split pre-amp/power amp offer flexibility when integrating other hi-fi components. Details like an independent headphone amplifier, a phonograph equaliser, three digital audio inputs, four analogue inputs, and gold-plated audio terminals/speaker posts speak of the highest build quality. The superb craftsmanship, technological refinement, and attention to detail invested in the A-9070 make it worthy of serious consideration for those in the market for top-shelf hi-fi gear.

Despite being beyond the normal range of human hearing, frequencies above 100 kHz are susceptible to clock pulse and other forms of distortion from digital devices. Such distortion in the super high frequency range can generate “beat interference”, which in turn affects the character or atmosphere of the original sound. By improving linearity and reducing distortion in the super-high frequency range, Onkyo’s new DIDRC technology effectively reduces perceptible noise.

2. Low Negative-Feedback Design

Too much NFB makes a system susceptible to counter-electromotive force from the speakers, resulting in a drop in perceived sound quality. To avoid this, Onkyo focuses on improving the frequency response and reducing distortion, without relying so much on NFB.

3. Closed Ground-Loop Circuits

The A-9070 employs a sophisticated closed-circuit design in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion.

4. HICC (High Instantaneous-Current Capability)

Handling current loads up to 100 amperes, HICC enables an amplifier to immediately cancel the speakers’ reflex energy and instantaneously send out the next signal. The same high current required to achieve this also supports the amplifier’s ability to handle speaker impedance fluctuations.

5. Symmetrical Twin-Monaural Construction

Power devices for the left and right channels of the A-9070 are aligned symmetrically. Each channel has the same electrical and structural design, and signal pathways are uniform in length. This helps to minimise errors in stereophonic playback.

With parallel “push-pull” amplification, the amplifier’s transistors alternately “push” and “pull” the current. In pairs, one output device (a transistor) will amplify the positive half of the waveform, while another output device amplifies the negative. Push-pull amplification is highly efficient, but can be affected by occasional instances of distortion. This is where the three-stage inverted Darlington circuitry comes in.Three-stage inverted Darlington circuitry actively works to reduce distortion by employing a low negative-feedback design to maintain voltage stability and enhance transient response. It’s extremely sensitive to oscillations and requires sophisticated control technology. Together with the push-pull amplifier design, the three-stage inverted Darlington Circuitry shapes a clean, consistent signal to send to the outputs.

Four Amplifier Modes for the Ultimate in Versatility

Boasting the combined capabilities of a pre-amp and a power amp, the A-9070 is an amplifier with a difference. At the turn of a knob, it can be configured to run in any one of four distinct modes. Depending on how you want to integrate it into your hi-fi system, you can use it as an integrated amp, as a power amp, or as a pre-amp. On top of that, you can also set up the A-9070 in split mode. This enables the pre-amp and power amp to work separately, so you can incorporate another device, such as an equaliser.

Separate Wolfson® 192 kHz/24-Bit DACs for L/R Channels

High-quality Wolfson DACs work to optimise analogue audio performance on the A-9070. The receiver features dual 24-bit WM8742 DACs, which support sampling rates of up to 192 kHz. Although these DACs are specified to handle two-channel audio on a single chip, Onkyo employs separate chips for each stereo channel to ensure the most accurate digital-to-analogue conversion.

New Circuit Board Construction

Rather than being directly connected to the chassis base, the circuit boards inside the A-9070 are cushioned by internal struts and affixed to the front, side, and rear panels. This method of construction prevents vibrations from the chassis from adversely affecting the circuit boards.

Audiophile-Quality Parts

To ensure optimal performance from the A-9070, Onkyo’s engineers incorporated a range of professional-grade parts. Four 15,000-microfarad capacitors and an extremely lowimpedance 0.05˝ (1.2 mm) thick copper bus plate both contribute to achieving a smooth and stable power supply. Machined and gold-plated RCA and phono terminals ensure an extremely clean connection.

At the heart of the evolved Q Series is the Uni-Q driver array. The signature innovation places the tweeter in the acoustic centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with any conventional speaker. Uni-Q's ultra-wide dispersion is further enhanced through KEF's 'tangerine' waveguide over the tweeter dome.

Damped tweeter loading tube

With the addition of the damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass.

New system design

The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass. Midrange clarity is enhanced again through improvements to the mid-bass driver that allowed the DC blocking capacitor to be eliminated. Its removal also created a more natural bass roll-off between the drivers.

Beefier LF drivers and ABRs

Low-frequency (LF) drivers now have a larger roll surround, along with a new suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension delivers better controlled and more impressive bass.
